The major threat associated with DNS forged responses or failures is the integrity of the DNS data returned in the response. If/when WINS lookups are enabled, the validity of the data becomes questionable since the WINS data is provided to the requestor, unsigned and invalidated. A DNS server is an example of an information system providing name/address resolution service. Digital signatures and cryptographic keys are examples of additional artifacts. DNS resource records are examples of authoritative data. Applications other than the DNS, to map between host/service names and network addresses, must provide other means to assure the authenticity and integrity of response data.
Log on to the DNS server using the Domain Admin or Enterprise Admin account. Press Windows Key + R, execute dnsmgmt.msc. On the opened DNS Manager snap-in from the left pane, expand the server name for the DNS server, and then expand Forward Lookup Zones. From the expanded list, right-click each zone, and then click “Properties”. In the “Properties” dialog box for the zone, click the “WINS” tab. Verify the "Use WINS forward lookup" check box is not selected. If the "Use WINS forward lookup" check box is selected, this is a finding.

unambiguously about these things.
